I see kernel 3.15 is now out, so I retested with 3.15 guest and host. I'm
still getting exactly the same guest kernel panic: a divide error in
kvm_unlock_kick with -cpu host, but not with -cpu qemu64:
divide error: [#1] PREEMPT SMP
Modules linked in:
CPU: 1 PID: 781 Comm: mkdir Not tainted 3
I realised my original bug report was for a guest kernel compiled without
frame pointers which might be unhelpful, so I enabled CONFIG_DEBUG_INFO and
CONFIG_FRAME_POINTER, but I don't think this has made the backtrace any more
detailed.
Is there anything more I can do to pinpoint what might be goi
